of the Republic of Switzerland, sid ng tv .C'ouven-in 'the Canton of Neucha- ""ep -of Switzerland, whose postress Couvet,'have invented cer- 'nd' useful Improvements in Valves `for?'lfneumatic Tires; and I do 'herebydeclare. the following to be a full, clear, and ,exact description of the invention, such as wlll enable others skilled in the -artv to which "it appert'ains to make and use the` same,

reference being: had to,'the accompanying drawings, .and to numeralsl of reference marked thereon, which form a part of this specification. Y l

This invention relates to' valves for. pneumatic vtire s,'aif1d has for its^object to design va valve, simple-1n construction-and with a bodyfportion of comparatively small diameter without, however, the 'flap or other parts being `made excessively small, and without the passage of the air being too greatly 'impeded during'the-iniation of the pneumatic tire.- p the accompanying drawings, Figure 1 is a partial section on the line e-f infFig. i4. andshowing the valve closed, while Fig. .2'. sh'ovvs theposivtion of `the valve during the inflation of a tire.

This headpieceis introduced into the pneul matic tire. .Nuts on the valve-body `serve to screw thesame tightly upon the pneumatic tire` and on tothe rim or telly.4 The valvebodyisbored axially throughoutits length, 'and is,l provided at its vupper endgwith a`- funnel-shaped enlargement which serves -as i -a seat for the inner valve-body 3. This. latter is furnished with an outside packing 4 ,and is Yforced against the seat of 'the outer valve-body by anut 5.V Varies 16ly1ng di-1 ametrically opposite each other and arranged 'onthef inner 'valve-body, enter. correspond- 'ing lots'l in the outer valve-body andpre'- ventthe inner valve-body rotating' when the screw-nut 5 is tightened; A- pacl'ring ring '1S placed between the valve-body'. 3 and ,the v screw-nut 5 prevents dust entering between the outer and the innervalve-bodiesfy Thus the.
